To wZZ-whom" it may concern.-

Be it known that 1, WILLIAM M. DECKER, of Kingston, in the county ofUlster and State of New York, have invented a new and use- .ful ImprovedNursing-Bottle, of which the following is a full, clear, and exactdescription. I

My. invention relates to improvements in bottles or like receptacles,used to contain liquid food that is to be fed to infants, and that areadapted to permit the gradual removal of such food by the child in theact of sucking a mouthpiece that is connected with thebottle.

Nursing devices may be said to involve generally two species: first,those with tubes entering the receptacle or cell, and second those knownas gravity devices. In the first species. the receptacle is emptiedentirely by suction while in the second the receptacle is emptied by thegravitation of the fluids to the nipple. v

My invention relates especially to the gravity species and has for itsobject to facilitate the gravitation of the fluid without obstruction,and consists of a cell or receptacle constructed without breast orneck,and closed by an elastic cover constituting an integral breast andnipple, substantially-similar to a mothers breast and nipple. As aresult of this construction the receptacle as well as its cover arecapable of ready and perfect cleansing, which is an all importantconsideration in administering artificial food to infants, and anotherresult is the ready flow of the fluids by gravity info the breast andnipple without necessitating the undue elevation of the receptacle andalso the avoidance of collapse of the nipple as the result of suction.

A further advantageous result of my invention consists in the fact thatthe infantis restricted to a natural hold on the nipple and it can onlyenter the mouth to a limited eX- tent and not so far as to gag orchokethe child, but to a sufficient distance to avoid ingestion of food byrestricting its discharge to the tongue and not beyond the tongueand'into the throat as occurs in the use of receptacles which may beforced into the mouth.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a partly sectional side view of the device. Fig. 2 is a sideview of the improvem ent taken'opposite the arrow 2 in Fig. 1. Fig. 3 isa detached side view of the top portion of the device. Fig. l'is a planview of the part shown in Fig. 3. Fig. 5 is aplan view of the receptaclehaving the cover portion removed. Fig.6 is a side view of theimprovement showing the upper part secured upon the lower portion withthe improved clamping device; and Fig. 7 is an enlarged detachedperspective view of the main por- 6r;

tidn of the clamping device.

The receptacle A, is constructed of glass or other approved material,without breast or neck and substantially rectangular in form, but may begiven a cylindrical or elliptical shape, having suitable dimensions forits use,

and for convenience in service vis made of a greater breadth thanthickness between parallel side walls, the wider 'part being shown inFig. 5, as defined. bythe space between the walls a, a, and the lesserdimension indicated by the distance between the parallel walls 17,12.The corners of the receptaclev A are all rounded, so as to avoid sharpangles and thus prevent material from lodging, and it is essential thatthe dimensions of the receptacle should be such as will permit the freeinsertion of the fingers of the person who is cleansing the vessel.

The bottom wall of the receptacle A, is flat, and of a sufficient areato afford a reliable base whereon the entire device may be sustained inan upright position on the horizontal surface of a stable support, suchas a table or like article.

The open upper end of the receptacle A, exclusive of its ribbedprojection, is preferably equal in area to a cross section taken at anypoint between its upperedge and one near to the curved corners at thebottom wall, and

from said edge a flange or rib c, is outwardly projected which has itslower side formed at a right angle to the body of the receptacle, and isrounded on the upper corner as shown in Figs. 1 and 6, where thereceptacle A is shown broken away.

The cover B, for the receptacle A, is normally of a conoidal form asshown in Figs.3 and 4; and consists of measurably thin, elastic materialsuch as vulcanized gum fabric. There is a circumferential rib d ofproper thickness formed on the free edge of the cover B, and therelative diameter of the latter is such as will permit its ribbed edgeto be stretched over the rib or flangec as indicated in Figs. 1, 2 and6.

The top portion of the conoidal cover B, is rendered coniform, andslightly contracted in diameter at a proper distance from its apex, thusproducing a mouthpiece C of conoidal form which is finely punctured atits upper terminal.

It will be seen that when the conoidal cover B, is stretched over thesubstantially rectangular ribbed upper end of the receptacle A, itslower portion will be caused to conform thereto by reason of the elasticand contractile nature of the material composing the cover, and the ribd on the latter will be drawn into close contact with the lower side ofthe flange or rib 0, so as to produce a liquid tight joint between theparts, thus producing a bottle with a colloidal top and a conoidalnipple or mouthpiece on the apex of said top.

As a measure of additional security, the clamping device shown in Figs.6 and 7, may be utilized to hold the parts A, B, together. Thiscomprises a band or cord 6 and a straining and locking piece E, thelatter consisting of a tubular link that is attached by one end tooneend of the clamping band, and has a vibratable bar 9, pivoted nearone of its ends within a slot longitudinally formed in said link, theother end of the band beingloosely inserted through the oppositeperforated end of the link and secured to the inner end of the bar g, sothat the folding of the latter upon the link body will draw upon thecord.

To apply the clamping device to the part B, the latter is drawn farenough below the rib 0 upon the receptacle A, to permit the band a to belocated between the ribs 0 and d, in contact with the exterior of thecover B. The length of the band e, should be such as will allow it toslightly bind upon the cover B when in position, and the bar 9 is swungaway from the link E, the band being caused to tighten upon the coverand bind it upon the receptacle A when the bar is folded upon said link,which folding movement will lock the bar against accidentaldisplacement, and retain the band in clamped condition until the bar islifted into the position shown in Fig. 7, and is swung farther towardthe end of the cord attached to the link.

By the peculiar construction of the said receptacle A, the interior canbe easily cleaned, and the cover B also, as the latter along with theintegral nipple C, can be turned inside out, so that all food particlesmay be washed from its inner side, and thus render the entire devicesweet and clean, which is a prime essential for the preservation ofhealth of the child fed from the said receptacle.

As the two parts comprising the improved nursing bottle are easilyseparated and connected, and the receptacle A is not contracted at itsopen end, it will be evident that itmay be filled with liquid foodwithout requiring a funnel, as it maybe dipped intoa vessel containingsaid food, or be filled to a proper height by pouring the latter intoit, a graduated scale on one side of the receptacle enabling theoperator to determine the proper quantity at sight by filling to acertain point on the scale.

The peculiar shapes of the parts comprising the improved nursing bottle,adapts it to deliver all its contents without obstruction, into the part0 and thence to the mouth of the user of the device.

Finally, it is claimed for this unique nursing bottle, that it embodiesin simple form and an inexpensive construction, a perfect sanitaryfeeding device for infants, which will obviate disease that results fromwant of proper assimilation of food, and that will permit a correctadministration of food in a perfectly clean condition.

I am aware of course that nursing bottles are not new in which the cellor food receptacle is contracted to form a breast and neck andsurmounted and closed by an ordinary elastic nipple, and do not wish tohave my invention confounded therewith. The gist of my invention, asbefore stated, liesin constructing the cell without any breast or neckand closing the open end thereof with a breast and nipple made integraland in form similar to a mothers breast and nipple, so that the entirecover is capable of compression and movement similar to the humanbreast, all of which results in securing at all times a proper and readyflow from the receptacle and rendering both the receptacle and its covercapable of ready and perfect cleansing.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A nursing device consisting of a cell orreceptacle having substantially an uncontracted and open upper portionclosed by an elastic breast of dome-shaped form, terminating at its apexin a perforated nipple, substantially as and for the purposes set forth.

2. In a nursing device, the combination, with a receptacle having anuncontracted open upper end and an elastic dome-shaped cover terminatingat its apexin a dome-shaped nipple, of a clamping device for the coverconsisting of apliable band and a locking bar pivoted in a slot of thelink and attached by its inner end to the other end of the band,substantially as described.

3. Asa new article of manufacture a cover for a nursing cell or foodreceptacle, consisting of an elastic dome-shaped breast open at its baseand adapted to embrace the cell, and terminated near its upper portionand made integral with a perforated nipple, substantially as and for thepurpose set forth.
